Gee, the early versions of Janus/Ada were *hosted* in 48K. Apparently, a
compiler is nothing useful??? ;-)
We studied this problem back in the day (30+ years ago).The problem is the
8051 architecture, which doesn't have a usable stack or the instructions to
make one. You would have to avoid recursion and any long chain of calls. Not
sure whether the result would program much like Ada, it would be much closer
to Fortran 66.
